Ester Dean has more bragging rights. A track penned by the singer-songwriter has made Rihanna’s new album.

“I just found out a couple days ago,” Dean told Rap-Up.com about making the cut. An official tracklisting for Rihanna’s fourth album Rated R, which also includes contributions from Tricky Stewart and The-Dream, Ne-Yo, Young Jeezy, will.i.am, and Slash, was released by Def Jam on Monday.

Track number eight, otherwise known as “Rude Boy,” was written by Dean, who’s penned hits for artists including Mary J. Blige, Pussycat Dolls, and Keri Hilson, and also has a hit of her own with “Drop It Low” featuring Chris Brown. The Rihanna track was produced by Stargate, she informed Rap-Up.com.

Dean additionally revealed that she is the writer behind Robin Thicke’s new song “Shakin’ It for Daddy” featuring Nicki Minaj. Her vocals can also be heard on the record.
